Anti-vaxxers use religious exemptions as false cover for their beliefs

For several years now, anti-vaxxers have been claiming that they have religious objections to vaccines. This is nonsense.

Just last month, the New England Journal of Medicinefeatured an article describing how the federal Equal Employment Opportunity Commission (EEOC) has been suing hospitals that deny employee requests for religious exemptions to the hospitals' vaccination requirements. The NEJMdocumented 14 cases where employees sued claiming that they had religious objections to the flu vaccine. Six of the cases were settled, and in the other cases, sometimes the hospital won, sometimes the employees. It's a mess.

What's really going on is that anti-vaxxers are using religious exemptions as cover for non-religious (and erroneous) objections to vaccines. The anti-vaxxers have convinced people that vaccines are harmful, or scary, or both. They are wrong.

Vaccines are the probably the greatest success story in the history of medicine. They've saved millions of lives. Consider that in the decade before the measles vaccine was introduced in 1963,

"3 to 4 million people in the United States were infected each year [and] an estimated 400 to 500 people died, 48,000 were hospitalized, and 1,000 suffered encephalitis (swelling of the brain) from measles." (Source: CDC)

And that's just measles. People no longer suffer and die from smallpox and polio, which have been eradicated worldwide (except for a few countries where polio still has a foothold). Vaccines protect us from multiple other formerly common childhood infections, and they've been so effective that people are no longer afraid of these diseases. That very success is the opening that the anti-vaxxers use to spread disinformation and fear.

It's not just the EEOC that has been enabling anti-vaxxers. Many U.S. states have passed laws that allow religious exemptions to vaccination. (Note that vaccines are required before children can enroll in public school systems, an incredibly important public health requirement. The exemptions refer to this requirement.)

New Jersey is the latest state to act. While the bill introduced in the New Jersey legislature last week doesn't quite eliminate religious exemptions, it makes them harder to get, requiring considerably more documentation from parents claiming a religious exemption from vaccines for their children. NJ took action after realizing that these so-called "religious" objections had risen dramatically, from 3,865 in 2009 to 10,407 in 2016. That rise was fueled, apparently, by anti-vaxxers taking advantage of the loophole in the law, not by any genuine religious objection to vaccines.

It's worth noting that all states allow medical exemptions to childhood vaccination, which are legitimate and necessary. For example, a child undergoing leukemia treatment may have a severely weakened immune system, and a vaccine would be ineffective and possibly harmful. These children are precisely the ones who can only be protected by requiring all the other children in their school to be vaccinated.

Meanwhile, the EEOC should stop suing hospitals. Hospitals are filled with very sick and vulnerable people, and employees have an obligation not to expose patients to possibly deadly infections. If a hospital employee doesn't take that obligation seriously, then s/he should find another job.
